CONSTRUCTION OF ARCHES.

SPECIFICATION forming part of Letters Patent No. 411,213, dated September 17, 1889. Application filed June 22,1889- Serial No. 315,135. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES BOGERT, of Yonkers, in the county of WVestchester and State of New York, haveinvented certain new and useful Improvements in the Construction of Arches, of which the following is a full, clear, and exact description.

My invention has for its object to provide a means whereby archessuch as memorial arches, for instancemay be built in a simple, expeditious, durable, and economical manner in an open space and stand firmly erect without the aid of abutments or tie-rods.

A further object of the invention is to construet a self-supporting arch and provide a means whereby the side irons of the frame will effectively sustain the weight and thrust of the arch at the spring, and wherein, also, the side irons or uprights or standards and the upper girder connecting the same will carry the entire weight of the material used in the construction of the arch.

The invention consists in the novel constructions and combinations of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the completed arch. Fig. 2 is a horizontal section on line 2 2 of Fig. 1. Fig. 3 is a central vertical section illustrating the frame in side elevation. Fig.4 is a vertical section on line 4 4 of Fig. 1. Fig. 5 is a vertical section 011 line 5 5 of Fig. 3. Fig. 6 is a horizontal section on line 0 6 of Fig. 3. Fig. 7 is a perspective view of a detached anchor, and Fig. 8 is a cross-section taken partially on line 8 S of In carrying out the invention a foundation is prepared consisting, preferably, of blocks 10, placed a distance apart essentially equal to the proposed inner width of the arch to be built. Upon each foundation the bases of two spaced parallel uprights or standards A are secured in any approved manner, each standard or upright consisting of two beams 11, of cast-iron, rolled iron, or boiler-iron, as

may be found advisable, which beams upon both side edges are provided with a longitudinal flange 12, extending beyond both side faces, as shown in Figs. 3 and (i. The beams are placed flange to flange, whereby a space 13 intervenes the contiguous faces of the bodies, and each set of beams constituting an upright or standard are connected an d rendered as on e beam by introducing washers into the space 13 and passing bolts or rivets 14 through the beams and washers, as is also shown in Fig. 6. The beams are preferably flanged at the lower end to form a frame or base 15, and the flan ges 12 upon the outer and inner face at the upper end are cutaway to permit of the attachment to the uprights of upper tie-girders B and diagonal brace-plates. One tie-girder is employed to unite the longitudinally-aligning uprights forming the side frames, and said girders consist of two beams 17 placed face to face, each provided with a longitudinal flange 1S, integral with the outer face at the top. The extremities of the united beams are introduced between the members of the uprights, the flanges being made to rest upon the upper edge of the uprights, as best illustrated in Figs. 5 and S, and the said girders and uprights areriveted,bolted, or otherwise secured together, as shown in Fig. 3.

It Will be observed that the frame as now constructed comprises two spaced parallel side uprights united at the upper ends by horizontal girders. To brace and strengthen the frame, a diagonal brace-plate 1.9 is located at each upper corner, secured at one extremity to the uprights and at the opposite end to the girders, and to said brace-plate 19, at or near the center, one end of a second brace-plate 20 is fastened, the other end being firmly secured to the side face of the uprights, preferably below their connection with the girders, as illustrated in Fig. 3. Masonry 21 of any de scription, preferably blocks of marble or other stone, is built around the uprights from the foundations 10, and from a suitable point in the altitude of the inner faces of the uprights the mason arch 22 is sprung, provided with the usual keystone 23, as best shown in Fig. 3.

A number of anchors 24 are employed in the construction of the arch, one of which is illustrated in detail in Fig. 7, and consists of a flat bar of metal bent upon itself at its upper end to form an angular hook 25, and provided with a twist 26 near its lower end, whereby the edge of the said lower end is at a right angle to the face of the body. The lower twisted end of an anchor is introduced between each stone formingthe arch proper 22, as shown in Fig. 3, and the hooked upper end is made to contact with and be supported upon either the uprights A, the brace-plates 19, or the girders B, according to the location of the stone to which the anchor is applied. The masonry 21 is carried upward beyond the upper end of the uprights and ends of the girders, as shown at 27, and the space between the girders and the span is also built up, as illustrated at 28 in Fig.

In order to lighten the weight sustained by the iron frame between the ends of the girders. and above the same, a hollow space 29 is left' in the masonry, the front and rear faces of the completed arch at this point being composed of thin slabs 30, as shown in Fig. 4, and likewise the top 31.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In the construction of an arch, the combination, with uprights and girders uniting the uprights, of diagonal brace-plates secured to the uprights and girders, and anchors secured to the brace-plates, girders, and uprights,'substantially as shown and described.

2. In the construction of an arch, the combination, with uprights and girders uniting the uprights, of diagonal brace-plates secured to the uprights and girders, and anchors carried by the brace-plates, the uprights, and girders consisting of a metal bar bent upon itself to form a hook at the upper end and twisted near the lower end, substantially as shown and described.

8. In the construction of arches, the combi nation, with uprights consisting of two longitudinally-flanged metal beams secured face to face, of girders uniting the uprights, comprising two L-shaped beams face to face passed between the members of the uprights and supported thereby, and anchors attached to the standards, and girders extending inward therefrom and adapted to tie the spring of the arch, substantially as shown and described.

4. I11 the construction of arches, the combination, with uprights consisting of two united beams having longitudinal flanges upon both faces, and girders uniting the uprights and supported thereby comprising two united beams, each having one longitudinal flange upon its outer face, of brace or tie plates secured to the uprights and girders, and anchors secured to the uprights, the girders and braceplates projecting inward therefrom, substantially as shown and described.

5. In the construction of arches, the combination, with uprights consisting of two united beams having longitudinal flanges upon both faces, and girders uniting and supported by said uprights, comprisin g two L-shaped beams introduced between the members of the uprights, of diagonal brace 01' tie plates secured to the uprights and girders, a solid casing surrounding the uprights and girders, having an arch sprung beneath the girders and between the uprights and provided with an upper compartment, and anchors secured to the uprights, the brace-plates, and girders, and to the members comprising the said arch, substantially as shown and described.
